  2. FIT ISSUES / APPLICATION TROUBLESHOOTING

I got a good fit with DenSureFit before, but now I can't get a good fit. Why?

If you have been able to achieve a good fit with DenSureFit on previous applications, but now you are not, there are a few reasons why your denture might fitting differently now.

There are 2 possible reasons for a change in how your DenSureFit-lined denture fits.

1) Changes in the mouth: Sometimes we have inflammation which we are not aware of. The gums are also constantly changing. The gum line can be fuller at some times and less full at other times. These changes can even vary depending on the time of day. If you apply your DenSureFit in the morning, your gums may be fuller than if you apply it in the evening, so evening may be a better time to for you to apply DenSureFit. When the gums shrink a little, it leaves looseness in the trough which then needs more silicone to get snug.

2) Issue with the application procedure: Sometimes, a very small issue in the application process can prevent an optimal fit. Most often, when someone tells us that they followed directions “to a TEE!”, we are actually able to help them identify an issue preventing them from achieving a great fit. This is where your awesome and amazing support team at DenSureFit comes in! We are thrilled If we can help you identify and resolve an application issue. We are passionate about customer service and this is GREAT NEWS for our customers because it means that together we can correct the issue and get you a great fit with a re-do! If you feel like it might be an application issue, read the Application Troubleshooting Guide below to see if you can find it. These are the most common issues that people encounter during the application process.

If you still have your DenSureFit in your denture, don't peel it out, yet. Please take some clear photos of the inside of your denture and the silicone inside of it and email them to help@densurefit.com so we can take a look at them. Let us know what the issue is that you are having and we will help you figure it out and hopefully fix it.

Sometimes all you need is an additional tube of silicone, especially if you are a newer denture wearer (still in the first 18 months post-extraction). If you are, you'll need a lot more silicone in the first year and a half then you will likely need after that, because gums are rapidly shrinking and one must replace that volume with silicone. Sometimes the foundation layer is not a great one and taking it out and starting fresh is necessary. We might be able to determine this from looking at your photos. This is the most common reason of not achieving the same good fit as before. As your gums continue to shrink, you'll need more silicone than you did before, because you need to replace the bone and tissue that you are losing with something....and that can be adhesive paste or DenSureFit silicone. Hopefully, you are making your life easier by filling it with silicone instead of adhesive.

Before you take a look at the Application Troubleshooting Guide below, please consider these scenarios to determine if you might fall into one of these situations:

  1. Are you overdue for a hard reline or a new denture? If so, it is still okay to use DenSureFit, but you might not achieve the perfect fit you desire, even though it may make it better and more comfortable. Some dentures are so big from gum shrinkage or so ill-fitting that they require a hard reline or a new denture altogether to achieve a good fit.
  2. DenSureFit is most effective when used between regular relines and adjustments from your dentist. It can make your denture more comfortable by providing cushioning and can greatly improve the fit in the interim if you need a hard reline or completely new denture. Unfortunately, DenSureFit isn’t designed or able to retrofit your denture in these types of situations and it is not our wish to sell our customers a product that isn’t going to meet their particular needs.
  3. One size does not fit all! Sometimes the basic application technique needs to be adjusted by the user as their mouth changes shape to get the best result for their unique situation. It could be that a re-application with customized adjustments might produce a better fit for you. We can help you to determine how to adjust your application so that it works the very best for you.

DenSureFit Application Troubleshooting Guide

Please carefully examine the DenSureFit inside of your denture to see if you can identify which issue(s) might pertain to your situation. If you can identify an issue, let us know! If you cannot, no worries. Either way, we will help you!

1) Did the silicone start setting up on your denture before you got it into your mouth?

Once you start expressing the silicone onto your denture, you must get the silicone onto your denture and into your mouth QUICKLY, before it starts setting up.

OOPs...set up outside of mouth

  • Explanation: The silicone sets up quickly. If it starts setting up outside of the mouth, it will not spread in its most fluid state, creating an uneven layer of silicone that is not an accurate impression. This will obstruct any chances of getting suction or a good fit.
  • Telltale Signs: Bare spots and/or humps of silicone on the palate or other places.
  • HOW TO FIX: Peel out your lining and start from scratch again according to the Instructions. This time apply the silicone and get your denture into your mouth QUICKLY.

2) If you applied a second applicator of silicone, WHERE did you apply it?

The first applicator of silicone gets applied to the palate and in the trough. This lays the foundation. After that, you should NEVER apply more silicone to the palate. It should ONLY be applied to the trough area.

  • Explanation: Too much silicone on the palate will make your palate too thick and will cause your denture to drop too low in your mouth, creating new voids in the trough. Your denture needs to fit as close to the roof of your mouth as possible with as THIN a layer of silicone as possible on the palate.
  • Telltale Signs: Visible thick layer of silicone on the palate, you feel like you have “horse-teeth” (they drop too low in your mouth), loss of suction, a denture that rocks, poor overall fit.
  • HOW TO FIX: Peel out your lining and start from scratch again according to the Instructions. If you apply a second or third applicator of silicone, carefully follow the SNUG-UP instructions in your booklet. After applying the first tube of silicone on the palate, apply ONLY to the trough area after that.

3) Did you seat your denture in the proper spot?

If your denture was not properly pressed up firmly into your suction spot during the curing process, your denture will not fit properly.

OOPS...didnt seat correctly

  • Explanation: The key to getting your best fit is to seat your denture ACCURATELY into your suction spot EVERY time you reline your denture and every time you give yourself a Snug-Up. Your denture is intended to stay in via suction. Suction happens in the highest, most curved part of the roof of your mouth, behind your gum line where your front teeth used to be. When you properly press your denture up into your suction spot during the curing process, it forces the silicone to fill the voids in the gum line in just the right spots so that your denture stays supported up in your suction spot. You will have a tendency to push back towards your throat, thinking that you need to fill the gap at the front of your teeth, so they do not stick out. RESIST THIS URGE! It will destroy your fit! Trust that your gap will be filled with the silicone when you add enough silicone and when it is in your suction spot.
  • Find your suction spot! Take your denture out of your mouth. Now, put your thumb inside on the roof of your mouth, and find that place behind your front gums where it is highest and curved. Your thumb likely fits right in that suction spot very well. Press UP towards the bridge of your nose and then press slightly forward. Now crook your index finger over the bridge of your nose with your thumb in that suction spot and press together firmly. This is the proper place to seat your denture while the silicone is setting up. Press your denture towards the bridge of your nose and slightly forward. You should NEVER push your denture back towards your throat.
  • Telltale Signs: Uneven silicone on the palate; ridges of silicone on the palate where you had applied lines of silicone; excessive silicone expressed over the ridge at the front of the teeth; poor overall fit.
  • HOW TO FIX: Peel out your lining and start from scratch again according to the Instructions. This time make sure that you are firmly pressing your denture up into your suction spot and then slightly forward when doing your initial application and any snug-up applications as well. NEVER push your denture back towards your throat.

4.) Did you apply the correct amount of silicone for your needs?

The proper amount of silicone is critical for getting a good fit. Too much or too little can create a poor fit.

OOPS...not enough silicone to fill voids

  • Explanation: If you are experiencing rocking or if your denture is popping up on one side, this is usually an indication that the voids in your trough are not yet completely filled on an area. When there is a void on one side or on the front or back, when pressure is placed on the opposite side, the denture will pop up or rock. This can even happen after you had a great initial fit. Your gums shrink at different rates in different places, so you may have an area with more shrinkage. After you get a good initial fit, if you experience rocking or popping up at a later date and lose some suction, your gums may have shrunk in that spot, creating a new void that needs to be filled. Once the void is filled while the denture is seated firmly in the suction spot, the trough/gum line is leveled out again for a much-improved fit.
  • Telltale Signs: When you push on one side, the other side pops up; or when you push on the front, the back pops up; or when you push on the back, the front pops up; or when you eat on one side, the other side pops up.
  • HOW TO FIX: Prepare your denture for adding more silicone as instructed. Clean, rinse, dry thoroughly. Add silicone to the area with the void. Seat firmly into suction spot for 4 minutes.
